Why can eating cheese prevent tooth decay?

A recent study by the American Dental Institute found that eating cheese increased alkalinity in the mouth - neutralizing tooth erosion acid, thus reducing the risk of tooth decay.

In the study, experts divided 68 children from 12-15 years into 3 groups: group 1 was asked to use a piece of cheese daily, group 2 used a sugar-free yogurt, the other group drank a cup milk and mouthwash daily.

The research team also measured pH on children's plaque before and after 10 minutes, 20 minutes and 30 minutes after using the above foods. The results showed that those who ate yogurt or milk did not have a change in pH in the mouth between two times before and after eating, said Vipul Yadav, the team leader. In contrast, children who used cheese showed a rapid increase in pH after each test.

The team believes that eating cheese increases the amount of saliva in the mouth - a natural method of the body to maintain a healthy oral pH. In addition, chewing cheese also releases chemical compounds that help create a protective film, thereby continuing to protect teeth against acid attacks on the enamel.
